PLOW ATTAC H M ENT.

SPECIFICATION forming part of Letters Patent No. 226,657, dated April20, 1880.

Application filed February 18, 1880.

To all whom it may concern Be it known that I, ALBERT F. FRoMM, ofCanton, in the county of Stark and State of Ohio, have invented certainnew and useful Improvements in Plow Attachments; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to letters of reference marked thereon, whichform a part of this specification.

Figure 1 of the drawings is a perspective view of a plow having myimproved attaclr ment. Fig. 2 is an elevation taken from the land sideof the plow.

In the drawings, A represents the beam, B the land-side, O themold-board, and D D the handles, of a plow, which may be, so far as myinvention is concerned, of any ordinary or convenient construction.

The main parts of my improved device consist of the three strongmetallic bars or plates E, F, and G. The part E is bent at 0, so as toprovide an upwardly and forwardly curved portion, E, substantially in avertical plane, and the part E substantially in a horizontal plane. Thisplate is secured to the plow-frame by means of a bolt or pivot at H, anda loop or metallic eye, I, secured to the plow-beam. The curved part Eextends forward and somewhat downward through the loop, wherein it maybe fitted tightly, or may be arranged to be adjusted to a limited extentby means of a pin and apertures, as shown.

The intermediate plate, F, of the attachment is secured to thehorizontal part E of the plate last described by means of bolts orset-screws ff, inserted through apertures in the part F and passingthrough a slot, 6, in the part E.

G represents the tooth beam or plate, which is hinged to the part F, asshown at 9. By means of this hinge the outwardly-projecting part of theattachment may be turned or folded up against the plow-frame when not inuse, as shown in dotted lines in Fig. 1. g g are tongues or armsprojecting from the inner end of the tooth-beam G some distance beyondthe 5 hingeg and beneath the plate F. They operate to prevent thefalling of the part G below the desired plane, causing it to be, so faras downward pressure is concerned, rigidly secured against the part F.

K K represent the teeth or supplemental plows, secured to the beam G bybolts and nuts similar to those shown at k, or in any preferred manner.

As the attachment is made to be used with plows of different sizes itisnecessary that the teeth should be adjustable relatively both to theplow and to each other, so that they can be properly set to coincidewith the ridges left by the plow. In my construction they are adjustedrelatively to the plow by means of the slotted bar E and the part F, andthey can be adjusted relatively to each other by means of the slots 9 inbar G and nuts 70 k.

L represents a weight attached to the outer end of the tooth-beam G. Iprefer to employ a metallic weight fastened to the beam by means ofscrew-threads or by permanently rivetin g it, although other means forsecuring it in place may be adopted, if desired. This weight not onlyserves to hold the teeth down to their work when in operation, but alsoserves to counterbalance and lock the hinged tooth-bar G in the uprightor inclined position occupied when it is folded back against theplow-frame during transportation and when the teeth are thrown out ofwork.

M is a spring, the fixed end of which is attached to the bar F by meansof a pivot, l. The spring is bent in such manner that it shall have anarm, L, adapted to be placed over and to bear downward upon thetooth-beam G and hold it to its work with any desired tension. L is ahandle formed with or attached to the outer end of the spring, wherebythe spring can be readily moved to or from the beam.

The hinge 9 permits the teeth, when they come in contact with stones orother obstructions, to rise, in order that they may pass over or escapesaid obstructions, and the spring L insures that after the teeth haveescaped they shall be instantly returned and held to their work again.

The handle D, to which the attachment is socured on the land side of theplow, is provided with a series of bolt-apertures, (shown at d,)

whereby the teeth may be set at any desired height, and by this means,in connection with the adjustability through the parts E and I, theteeth may be set at any desired angle to the plane of the plow. The slot0 in the part E and the screws ff permit the tooth-beam and the teeth tobe adjusted to any desired distance from the plow.

From the foregoing description and an examination of the drawings itwill be seen that my improved attachment may be instantly removed bywithdrawing a single bolt from the frame of the main plow, thus leavingthe plow entirely freed from the parts necessary to support or operatethe finishin g attachment.

It will be seen, moreover, that, owing to the peculiar shape of the baror plate E, I am enabled to support the attachment horizontally from theinside of the plow without its being liable to disastrous results fromlateral strain upon the barrow-teeth, the vertical bar or plate Eenabling me to dispense with the complicated devices necessary tosupport the toothframe when it is attached to the plow on the mold-boardside.

I am aware that harrowing attachments of various kinds have beenheretofore combined with plows, and I do not wish to be understood asclaiming any of these devices, broadly, as my invention.

What I claim is- 1. The combination, with the bar E, having the verticalpart E, arranged to be secured.

against the land side of the beam and handle of an ordinary plow, andthe horizontal part E extending across the plow, of the bar F,adjnstably secured to the horizontal part E and the tooth-bar Gr, hingedto the adjustable part F, substantially as set forth.

2. The combination of the bar E, rigidly attached to the plow, the barF, adjustably attached to the bar E, and the tooth-bar G, attached toadjustable bar F by a hinge, and provided with the stops orlocking-projections g g, substantially as set forth.

3. The combination, with a plow, of supplemental teeth arranged to beadjusted relatively to the plow by means of an extensiblesupporting-frame, and adjustable relatively to each other independentlyof the frame, substantially as set forth.

4:. In an attachment for plows, the combination, with the stationary oarF and the tooth.- bar Gr, hinged to the bar F, of the spring M, pivotedat one end to the stationary bar F, and having its free end arranged tobear against the hinged tooth-bar when the teeth are at work and to beremoved from said bar by a lateral rotation to allow the teeth to bethrown out of work, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand.
